I think it's very important! I've been unhappily married for 27 years and never had a great sex life but we completely stopped having sex over 10 years ago. I feel nothing for him anymore. We are friends and not even good ones at that! Sex is the glue among other things that holds your relationship together I think. I envy people that are lucky enough to have that
I'd put it up there on the podium. Of course, I'm not talking about the act. I'm talking about the things that make the physical act so good. You can pay for sex, but you can't pay for honesty, love, trust, caring, kindness, understanding, belief & respect in another.
It plays an important role. I wouldn't say it's the make or break of the relationship. I agree with most of the answers here that it is important BUT then more so on honestly, loyalty, trust, love, caring, kindness, understanding, compromise, respect and all that jazz.
Teens tend to exploit this aspect of a relationship to justify and CLAIM of their love. They have NO IDEA how WRONG they are.
It depends on how important you want to make it in your relationship. If you solely build a relationship around sex then that relationship will fail. Now, if you are just looking to hook up for a good time then it's pretty important. However, taking the step into a sexual relationship is a big one. It's something that you need to make sure that you and your partner are both ready for.
